El-Sayed Glacier
The Land Glacier () is a broad, heavily crevassed glacier, about long, descending into Land Bay in Marie Byrd Land, Antarctica. It was discovered by the United States Antarctic Service (1939–41) and named for Rear Admiral Emory S. Land, Chairman of the United States Maritime Commission. Location The Land Glacier flows north from the ice field to the northeast of the west-flowing Balchen Glacier and Crevasse Valley Glacier. Milan Rock is to the east of its upper section. It flows past the west side of the ridge that includes Mount Hartkopf, Pearson Peak (formerly Mount Pearson), McGraw Peak and Mount McCoy, where it is joined from the east by the combined Paschal Glacier and White Glacier. Castillo Point defines the eastern point of its mouth. From its west it is joined by Farbo Glacier and El-Sayed Glacier, which both descend from the heights of Zuncich Hill and McGee Rock. Between these two, it saddles at Parker Pass with the west-flowing Siemiatkowski Glacier. Bruner Hil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marie Byrd Land
Marie Byrd Land (MBL) is an unclaimed region of Antarctica. With an area of , it is the largest unclaimed territory on Earth. It was named after the wife of American naval officer Richard E. Byrd, who explored the region in the early 20th century. The territory lies in West Antarctica, east of the Ross Ice Shelf and the Ross Sea and south of the Pacific Ocean portion of the Antarctic or Southern Ocean, extending eastward approximately to a line between the head of the Ross Ice Shelf and Eights Coast. It stretches between 158°W and 103°24'W. The inclusion of the area between the Rockefeller Plateau and Eights Coast is based upon Byrd's exploration. Overview Because of its remoteness, even by Antarctic standards, most of Marie Byrd Land (the portion east of 150°W) has not been claimed by any sovereign state. It is by far the largest single unclaimed territory on Earth, with an area of , including Eights Coast, immediately east of Marie Byrd Land. In 1939, United States ...

Névé
Névé is a young, granular type of snow which has been partially melted, refrozen and compacted, yet precedes the form of ice. This type of snow can contribute to glacier formation through the process of ''nivation''. Névé that survives a full season of ablation turns into firn, which is both older and slightly denser. Firn eventually becomes glacial ice – the long-lived, compacted ice that glaciers are composed of. Glacier formation can take years to hundreds of years, depending on freeze-thaw factors and snow-compaction rates. Névé is annually observed in skiing slopes, and is generally disliked as an icy falling zone. Névé has a minimum density of 500 kg/m3, which is Density#Water, roughly half of the density of liquid water at 1 Atmosphere (unit), atm. Névé can also refer to the Alpine climate, alpine region in which snowfall accumulates, becomes névé, and feeds a glacier. See also * Suncup (snow), Suncup Notes External links * Névés, ...

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...
